public class inttoObject
{
public static void main(String[] args)
{
int x=90;
Object o;
o=90;
System.out.println(o);
}
}


How a primitive like 'int' can be assigned to a 'Object' reference?

I would guess that '90' is being autoboxed into an Integer, and that is getting assigned to the Object reference.

I think what is happening here is; since everything is a subclass of Object the compiler is seeing Object 0 as 90. the int x = 90; is not relevant?

I could be wrong, just my take.

This compiles and outputs 90.
